Despite Its Newfound Love For Windows Phone, The iPhone Is Still AT&T’s Bread & Butter

AT&T seemingly snubbed the iPhone earlier this year, choosing instead to focus its efforts on Nokia’s latest Lumia 900 handset running Microsoft’s Windows Phone operating system. The carrier promised the device would be a “notch above” Apple’s popular handset, but as things currently stand, the iPhone is still its bread and butter, making up over 78% of its smartphone activations in the last quarter.

AT&T has announced this morning that it sold 5.5 million smartphones during the last quarter, which ended on March 31. Of which 4.3 million were the iPhone, accounting for 78% of its smartphones sales. Maybe, then, AT&T shouldn’t be so quick to turn its back on Apple’s device in favor of Nokia and Windows Phone.

And there’s no sign of easing demand, either, with year-over-year sales up by 0.7 million units. AT&T remains the most popular carrier for the iPhone. Verizon came in second after shifting 2.2 million devices during the same three-month period.

AT&T saw $31.8 billion in consolidated revenues, which is $575 million more than it saw in the same quarter last year. Wireless revenues are up 5.4% year-over-year to $16.1 billion, of which $6.1 billion is from data revenues.
